Mis-adjusted valves won't affect your valve guides. About four hours shop labor to rebuild the head if you chose. If me, I'd just roll with it. You're nick name will be "Smokey Joe".
Ok, so putting the timing mark in the center of the inspection hole isn't exactly enough, right? I think what I am missing, is ensuring that it's tdc on the compression stroke. Please pardon my lack of knowledge, but, how do I know if it's the compression stroke?
